The Effect of Rating Method on Reliability of Judgments of Strain Across Populations.

PURPOSE: Variability in auditory-perceptual ratings of voice limits their utility, with the poorest reliability often noted for vocal strain. The purpose of this study was to determine whether an experimental method, called visual sort and rate (VSR), promoted stronger rater reliability than visual analog scale (VAS), for ratings of strain in two clinical populations: adductor laryngeal dystonia (ADLD) and vocal hyperfunction (VH). METHOD: Connected speech samples from speakers with ADLD and VH as well as age- and sex-matched controls were selected from a database. Fifteen inexperienced listeners rated strain for two speaker sets (25 ADLD speakers and five controls; 25 VH speakers and five controls) across four rating blocks: VAS-ADLD, VSR-ADLD, VAS-VH, and VSR-VH. For the VAS task, listeners rated each speaker for strain using a vertically oriented 100-mm VAS. For the VSR task, stimuli were distributed into sets of samples with a range of severities in each set. Listeners sorted and ranked samples for strain within each set, and final ratings were captured on a vertically oriented 100-mm VAS. Intrarater reliability (Pearson's r) and interrater variability (mean of the squared differences between a listener's ratings and group mean ratings) were compared across rating methods and populations using two repeated-measures analyses of variance. RESULTS: Intrarater reliability of strain was significantly stronger when listeners used VSR compared to VAS; listeners also showed significantly better intrarater reliability in ADLD than VH. Listeners demonstrated significantly less interrater variability (better reliability) when using VSR compared to VAS. No significant effect of population or interactions was found between listeners for measures of interrater variability. CONCLUSIONS: VSR increases intrarater reliability for ratings of vocal strain in speakers with VH and ADLD. VSR decreases variability of auditory-perceptual judgments of strain between inexperienced listeners in these clinical populations. Future research should determine whether benefits of VSR extend to voice clinicians and/or clinical settings.

The Development of Head and Neck Cancer in Patients with the Isolated Complaint of Globus Pharyngeus.

OBJECTIVES: Globus pharyngeus (GP) is a perplexing problem that accounts for 4% of referrals to otolaryngologists. Workup can be extensive and may not be definitive in terms of etiology. The concern that lingers is that of a subtle cancer, which can prolong anxiety and increase testing cost. The aim of this study was to identify the incidence of head and neck cancer (HNC) in patients diagnosed with GP. METHODS: Longitudinal data were captured from two academic institutions, identifying patients with a new diagnosis of globus pharyngeus in 2015. The patient cohort was tracked for at least 4 years to assure follow-up and ability to determine if a HNC developed. Additional demographic data was also collected to determine most common consults, treatments, and testing employed. RESULTS: Excluding patients with previous diagnosis of HNC, 377 patients were identified who presented with GP in 2015 that had at least 4 years of follow-up. Demographics were predominantly women (64.65%), with a mean age of 56.48 years at diagnosis, and the most common provider specialty on the first visit was otolaryngology (39.52%). Four patients ultimately developed HN cancer, for an overall incidence of 1% for the 4-year period of 2015-2019. CONCLUSIONS: Given the long-term follow-up of this population, the overall incidence of developing a head and neck cancer, with a presenting symptom of globus, is low. This is the largest study to date to report the percentage of patients endorsing GP to then subsequently develop HNC. This helps otolaryngologists to reassure patients who have a normal comprehensive exam, flexible endoscopy, and targeted studies. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:1147-1154, 2024.

Assessment of Patients Receiving Short-Interval Botulinum Toxin Chemodenervation Treatment for Laryngeal Dystonia and Essential Tremor of the Vocal Tract.

Importance: The gold-standard treatment for laryngeal dystonia (LD) and essential tremor of the vocal tract (ETVT) is botulinum toxin (BoNT) chemodenervation. Although safe and effective, it is not curative, and periodic injections are required. Some medical insurance companies only cover injections at a 3-month interval, though some patients benefit from injections more frequently. Objective: To determine the proportion and characteristics of patients who receive BoNT chemodenervation treatment in intervals shorter than 90 days. Design, Setting, and Participants: This retrospective cohort study across 3 quaternary care neurolaryngology specialty practices in Washington and California recruited patients who underwent at least 4 consecutive laryngeal BoNT injections for LD and/or ETVT in the past 5 years. Data were collected from March through June 2022 and analyzed from June through December 2022. Exposure: Laryngeal BoNT treatment. Main Outcomes and Measures: Biodemographic and clinical variables, injection characteristics, evolution during the 3 interinjection intervals, and lifetime laryngeal BoNT treatment data were collected from patient medical records. Logistic regression was used to assess association to the short-interval outcome, defined as an average injection interval shorter than 90 days. Results: Of 255 patients included from the 3 institutions, 189 (74.1%) were female, and the mean (SD) age was 62.7 (14.3) years. The predominant diagnosis was adductor LD (n = 199 [78.0%]), followed by adductor dystonic voice tremor (n = 26 [10.2%]) and ETVT (n = 13 [5.1%]). Seventy patients (27.5%) received short-interval injections (<90 days). The short-interval group was younger than the long-interval group (≥90 days), with a mean (SD) age of 58.6 (15.5) years and 64.2 (13.5) years, respectively, and a mean difference of -5.7 years (95% CI, -9.6 to -1.8 years). There were no patient-related differences between the short- and long-interval groups in terms of sex, employment status, or diagnosis. Conclusions and Relevance: This cohort study demonstrated that while insurance companies often mandate a 3-month or greater interval for BoNT chemodenervation financial coverage, there is a considerable subset of patients with LD and ETVT who receive short-interval treatment to optimize their vocal function. Short-interval chemodenervation injections demonstrate a similar adverse effect profile and do not appear to predispose to resistance through antibody formation.

Treatments for Age-related Vocal Atrophy: A Systematic Review.

OBJECTIVE: Age-related vocal atrophy (ARVA) can dramatically affect voice, communication, and quality of life. The objectives of this systematic review were to (1) determine whether treatments for ARVA were superior to controls (2) compare the relative efficacy of procedural and behavioral treatments (3) review the various types of outcome measures, and (4) evaluate the quality of studies. REVIEW METHODS: The literature was searched using strategies designed by a medical librarian (2/18/21, updated 3/9/22). Studies investigating treatments for bilateral vocal atrophy were included. Studies involving unilateral atrophy, presbyphonia (without endoscopic findings), or an absent comparator group were excluded. The Preferred Reporting Items for Systematic Reviews and Meta-analyses checklist was used to guide this study. RESULTS: After applying the inclusion/exclusion criteria, 8 articles remained, including 4 randomized trials and 4 cohort studies, and a narrative synthesis was performed. Surgical and behavioral treatments for ARVA appeared to be superior to control groups, based on specific outcome measures. However, the superiority of these treatments over controls was not uniformly observed across multiple outcome measures. When comparing different treatments, superiority could not be established based on the quality and completeness of the studies included in the systematic review. Outcome measures also varied between individual studies. Finally, the risk of bias was analyzed and scored. Consistent point deductions among reviewed studies were noted. CONCLUSIONS: When comparing treatments for ARVA. Surgery and voice therapy were both superior to control groups based on specific outcome measures from different domains. Superiority of one treatment could not be established. LEVEL OF EVIDENCE: N/A Laryngoscope, 133:2846-2855, 2023.

Defining the Performance of Clinician's Ability to Screen for Laryngeal Mass From Voice.

OBJECTIVE: Defining a clinician's ability to perceptually identify mass from voice will inform the feasibility, design priorities, and performance standards for tools developed to screen for laryngeal mass from voice. This study defined clinician ability of and examined the impact of expertise on screening for laryngeal mass from voice. STUDY DESIGN: Task comparison study between experts and nonexperts rating voices for the probability of a laryngeal mass. SETTING: Online, remote. METHODS: Experts (voice-focused speech-language pathologists and otolaryngologists) and nonexperts (general medicine providers) rated 5-s/i/voice samples (with pathology defined by laryngoscopy) for the probability of laryngeal mass via an online survey. The intraclass correlation coefficient (ICC) estimated interrater and intrarater reliability. Diagnostic performance metrics were calculated. A linear mixed effects model examined the impact of expertise and pathology on ratings. RESULTS: Forty clinicians (21 experts and 19 nonexperts) evaluated 344 voice samples. Experts outperformed nonexperts, with a higher area under the curve (70% vs 61%), sensitivity (49% vs 36%), and specificity (83% vs 77%) (all comparisons p < .05). Interrater reliability was fair for experts and poor for nonexperts (ICC: 0.48 vs 0.34), while intrarater reliability was excellent and good, respectively (ICC: 0.9 and 0.6). The main effects of expertise and underlying pathology were significant in the linear model (p < .001). CONCLUSION: Clinicians demonstrate inadequate performance screening for laryngeal mass from voice to use auditory perception for dysphonia triage. Experts' superior performance indicates that there is acoustic information in a voice that may be utilized to detect laryngeal mass based on voice.

Exploring female otolaryngologists' experiences with gender bias and microaggressions: a cross sectional Canadian survey.

BACKGROUND: Gender bias is behavior that shows favoritism towards one gender over another. Microaggressions are defined as subtle, often unconscious, discriminatory, or insulting actions that communicate demeaning or negative attitudes. Our objective was to explore how female otolaryngologists experience gender bias and microaggressions in the workplace. METHODS: Anonymous web-based cross-sectional Canadian survey was distributed to all female otolaryngologists (attendings and trainees) using the Dillman's Tailored Design Method from July to August of 2021. Quantitative survey included demographic data, validated 44-item Sexist Microaggressions Experiences and Stress Scale (MESS) and validated 10-item General Self-efficacy scale (GSES). Statistical analysis included descriptive and bivariate analysis. RESULTS: Sixty out of 200 participants (30% response rate) completed the survey (mean age 37 ± 8.3 years, 55.0% white, 41.7% trainee, 50% fellowship-trained, 50% with children, mean 9.2 ± 7.4 years of practice). Participants scored mild to moderate on the Sexist MESS-Frequency (mean ± standard deviation) 55.8 ± 24.2 (42.3% ± 18.3%), Severity 46.0 ± 23.9 (34.8% ± 18.1%), Total 104.5 ± 43.7 (39.6% ± 16.6%) and high on GSES (32.7 ± 5.7). Sexist MESS score was not associated with age, ethnicity, fellowship-training, having children, years of practice, or GSES. In the sexual objectification domain, trainees had higher frequency (p = 0.04), severity (p = 0.02) and total MESS (p = 0.02) scores than attendings. CONCLUSIONS: This was the first multicenter, Canada-wide study exploring how female otolaryngologists experience gender bias and microaggressions in the workplace. Female otolaryngologists experience mild to moderate gender bias, but have high self-efficacy to manage this issue. Trainees had more severe and frequent microaggressions than attendings in the sexual objectification domain. Future efforts should help develop strategies for all otolaryngologists to manage these experiences, and thereby improve the culture of inclusiveness and diversity in our specialty.

Otolaryngology residents' experiences of pregnancy and return to work: A multisite qualitative study.

Objectives: A paucity of literature exists about childbearing during otolaryngology residency. Pregnancy is a common part of many physician life cycles, but the timing of residency and the rigors of surgical training amplify the challenges. This study was designed to understand the experiences of childbearing otolaryngology residents and support them during this major life event. Unique challenges include long training, shortage of role models, combination surgical and clinical work, and higher rates of infertility. Study Design: Qualitative research. IRB exempt. Setting: United States. Methods: To capture modern perspectives, 16 current and former otolaryngology residents that experienced pregnancy and childbirth during residency in all four geographic regions of the United States in the past 10 years were recruited to participate in individual structured qualitative interviews. Results: Although there was significant training program and personal anxiety reported by childbearing otolaryngology residents, many surgeons experienced healthy pregnancies and postpartum recoveries with minimal disruption to clinical productivity and minimal disruption to their training programs. Multiple recurring themes were identified among the participants spanning the entire childbearing process: increased incidence of pregnancy complications and preterm labor, pregnancy stigma from leadership and coresidents, scheduling logistics regarding call and parental leave, and challenging transitions back to clinical work while navigating breastfeeding and childcare. Conclusion: There are actional recommendations that programs can address to make childbearing during residency accessible and acceptable. Understanding these challenges is an important step to encouraging childbearing residents to prosper in academic otolaryngology, increasing the diversity at the highest levels of the field. Level of Evidence: 4.

Tracheotomy care simulation training program for inpatient providers.

Objectives: Tracheotomy complications can be life-threatening. Many of these complications may be avoided with proper education of health care providers. Unfortunately, access to high-quality tracheotomy care curricula is limited. We developed a program to address this gap in tracheotomy care education for inpatient providers. This study aimed to assess the efficacy of this training program in improving trainee knowledge and comfort with tracheotomy care. Methods: The curriculum includes asynchronous online modules coupled with a self-directed hands-on simulation activity using a low-cost tracheotomy care task trainer. The program was offered to inpatient providers including medical students, residents, medical assistants, nurses, and respiratory therapists. Efficacy of the training was assessed using pre-training and post-training surveys of learner comfort, knowledge, and qualitative feedback. Results: Data was collected on 41 participants. After completing the program, participants exhibited significantly improved comfort in performing tracheotomy care activities and 15% improvement in knowledge scores, with large effect sizes respectively and greater gains among those with little prior tracheotomy care experience. Conclusion: This study has demonstrated that completion of this integrated online and hands-on tracheotomy simulation curriculum training increases comfort and knowledge, especially for less-experienced learners. This training addresses an important gap in tracheotomy care education among health care professionals with low levels of tracheotomy care experience and ultimately aims to improve patient safety and quality of care. This curriculum is easily transferrable as it requires only access to the online modules and low-cost simulation materials and could be used in other hospitals, long-term care facilities, outpatient clinics, and home settings. Level of evidence: 4.

Implementing a "Distance Traveled" Question to Improve Resident Diversity: Process and Feasibility.

Increasing diversity in the physician workforce is important to improving racial and ethnic disparities in health outcomes in the United States. We describe the implementation of a "distance traveled" question (DTQ) in our residency application process. For the 2021-2022 cycle, all applicants to the University of Washington otolaryngology residency program were allowed to complete an optional DTQ. Responses were shared with the application review committee. Following the distribution of interview invites, an anonymous survey was sent to all faculty reviewers. The response rate was 26 of 36 (72%). Among respondents, 20 (77%) felt that the DTQ helped them learn something new about the applicant, and 19 (73%) reported that the DTQ influenced their decision making about the applicant. Thus, a DTQ may provide faculty with new and influential information regarding residency applicants.

Durable response in a patient with recurrent respiratory papillomatosis treated with immune checkpoint blockade.

BACKGROUND: Immune checkpoint blockade can provide clinical benefit for patients with advanced cancer. Here, we report durable disease control over many years following PD-L1 blockade through induction of a viral antigen-specific T cell response in an adult patient with recurrent respiratory papillomatosis. METHODS: Antigen-specific T cell response assays, single cell RNA-sequencing, and RNA-scope was used to study clinical tissues. RESULTS: An HPV6 E2-specific T cell clone restricted to HLA-B*55, present at low frequency in the pre-treatment papilloma, significantly expanded after six doses of PD-L1 blockade and remained present and functional at the site of initial response in the larynx as a tissue resident memory T cell for 4 years. An associated reduction in E2 target gene was observed following treatment. CONCLUSIONS: Although demonstrated in a single exceptional responder, these results highlight that immune checkpoint blockade may induce durable, viral antigen-specific immunity of sufficient magnitude to control disease in patients with nonmalignant disorders.

Update on Tracheostomy and Upper Airway Considerations in the Head and Neck Cancer Patient.

Patients with head and neck cancer account for a large proportion of perioperative airway events. Further, these patients frequently require tracheostomy placement, which is one of the most common surgical procedures. This article reviews updated techniques in managing a difficult airway in patients with head and neck cancer, such as strategies for intubation/extubation, methods of tubeless laryngeal surgery, and techniques and relevant topics in tracheostomy management.

Improvement in Work Productivity After Group Voice Therapy in Professional Voice Users.

OBJECTIVE: A disordered voice may significantly impair the ability of workers to perform optimally on the job, especially those classified as professional voice users (PVU). Voice therapy is a common treatment option for voice disorders, but there are few studies demonstrating its effect on work productivity. The objective of this study was to evaluate the change in work productivity in PVU after group voice therapy. STUDY DESIGN: Prospective cohort study SETTING: Academic Voice Center METHODS: PVUs whose primary treatment for their voice disorder was voice therapy were recruited. Participants completed a 7-week group voice therapy course from January 2018 to December 2020. Participants completed the validated Work Productivity and Activity Impairment questionnaire (WPAI) which measured presenteeism (on the job work productivity impairment) and absenteeism (time missed from work), general self-efficacy scale (GSES), and Voice handicap index -10 (VHI-10) before and after group voice therapy. Changes in scores before and after therapy were compared using a Wilcoxon Signed-Rank test. RESULTS: Twenty-seven PVU were recruited; 25 had complete data (100% female, mean age 45.4 years, 68% teachers). Presenteeism (SD) decreased from 72.0% (23.3) to 36.8% (24.8), which represented a significant improvement of 35.2% (27.8) [95% CI 21.7-38.7; P < 0.001]. Activity impairment decreased from 48.4% (32.0) to 25.6% (23.8), which represented a significant improvement of 22.8% (26.5) [95% CI 20.7-37.0; P < 0.00]. There was no change in absenteeism (P = 0.27). Patients had high mean GSES of 34.4 (3.7) and abnormal mean VHI-10 of 18.2 (7.2). Changes in VHI-10 and GSES were not significant. CONCLUSION: PVU had an improvement in work productivity that was largely represented by decreased presenteeism after completing group voice therapy.

Evaluating the Effect of Recurrent Respiratory Papillomatosis on Work Productivity.

OBJECTIVE: Patients with recurrent respiratory papillomatosis (RRP) have significant vocal dysfunction which affects their performance at work. This study aimed to evaluate voice-related work productivity before and after ablative treatment for RRP. METHODS: This is a prospective case series conducted at 2 academic laryngology outpatient clinics. Adult employed patients with RRP completed the Work Productivity & Activity Impairment instrument (WPAI), Voice Handicap Index (VHI-10), WorkHoarse, Hospital Anxiety and Depression Scale (HADS), and a demographics questionnaire immediately before and 1 month after ablative treatment of papilloma. The primary outcome measure was the change in work productivity impairment domain of the WPAI, and changes in ratings before and after ablation were compared using a Wilcoxon Signed-Rank test. RESULTS: The 32 participants (mean age 45, 84% male) had a median (interquartile range) voice-related work productivity impairment score of 48.8% (30.0) at baseline which was improved to 5.0% (10.0) at 1 month after surgical ablation of papillomata (difference 30.0% (30.0) improvement). For the secondary outcome measures, there were significant improvements in VHI-10 (P < .001), self-reported voice quality (P = .002), and Workhoarse (P = .001), but no significant change in HADS. CONCLUSION: Patients with RRP experience significant voice-related work productivity impairment, and ablation of papillomata significantly improves work productivity.

Sensitivity of the Communicative Participation Item Bank for Measuring Patient-Reported Outcomes After Treatment of Unilateral Vocal Fold Immobility.

Importance: The Communicative Participation Item Bank (CPIB) is a patient-reported outcome measure assessing the association between communication disorders and participation in daily communication. To our knowledge, no prior research has examined whether CPIB scores change after treatment of unilateral vocal fold immobility (UVFI). Objective: To compare CPIB scores before and after treatment of UVFI and with patient-defined target treatment outcomes and other common clinical outcomes after UVFI intervention. Design, Setting, and Participants: This single-group case series recruited a convenience sample of community-dwelling patients aged 18 years or older from an urban academic medical center who had a diagnosis of UVFI and planned to receive intervention for UVFI. The study was conducted from March 2014 to March 2019. Exposures: Intervention for UVFI according to clinicians' recommendations. The treatment type was not controlled for this study. Main Outcomes and Measures: Patients' self-reported communicative participation was assessed by obtaining CPIB scores before and after treatment of UVFI, with scores calibrated to the standardized T scale. Pearson correlations between the CPIB general short form and computerized adaptive format, the Voice Handicap Index-10 (VHI-10), and self-rated and clinician-rated voice severity were also evaluated. Results: The sample included 25 participants, of whom 17 (68%) were male, 8 (32%) were female, and the mean (SD) age was 54.9 (17.0) years. Significant changes after treatment were observed in all quantitative outcomes including the primary outcome of the CPIB; the mean T score before treatment was 40.95 (95% CI, 37.49-44.41) and after treatment was 53.23 (95% CI, 48.41-58.04) (mean difference, -13.04 [95% CI, -7.30 to -18.79]; Cohen d, 0.96). The Pearson correlation between the CPIB general short form and computerized adaptive testing scores at pretreatment was r = 0.93 and at posttreatment, r = 0.95. Computerized adaptive testing showed efficiency advantages, with typically 5 to 6 items required for administration compared with 10 items for the short form. The correlation between the CPIB and VHI-10 was moderate before treatment (r = -0.70) and strong after treatment (r = -0.91). Moderate correlations were observed between the CPIB and clinician-rated voice quality before (r = -0.52) and after (r = -0.46) treatment and between CPIB and self-rated voice quality before (r = -0.56) and after (r = -0.62) treatment. Conclusions and Relevance: The results of this case series suggest that the CPIB is relevant for clinical use to assess changes in communicative participation among patients with UVFI before and after they receive treatment.

Association of Laryngeal Botulinum Neurotoxin Injection With Work Productivity for Patients With Spasmodic Dysphonia.

Importance: A disordered voice can affect an individual across both work and non-work-related life domains. There is insufficient research on the effect of spasmodic dysphonia or its treatment with botulinum neurotoxin (BoNT) injections on work productivity. Objective: To assess whether employed patients with spasmodic dysphonia experience voice-related work productivity impairment before BoNT injection, and had a 10% or greater improvement in productivity 1 month after treatment with BoNT injection. Design, Setting, and Particpants: This prospective case series carried out in 2 laryngology outpatient clinics from November 1, 2015, to August 30, 2018 included a consecutive sample of adult employed patients diagnosed with spasmodic dysphonia. Analysis was conducted between November 1, 2015, to July 31, 2018. Exposures: Treatment with BoNT injection into the intrinsic laryngeal musculature. Main Outcomes and Measures: Eligible participants completed the following validated outcomes instruments immediately before and 1 month after outpatient laryngeal BoNT injection: the Work Productivity and Activity Impairment instrument (WPAI), Voice Handicap Index (VHI), and WorkHoarse. Demographic, comorbidity, and occupational voice use data were also collected at baseline. The changes in outcome measures (primary, WPAI Work Productivity Impairment domain) were tested using a paired 2-tailed t test. Exploratory subgroup analyses were analyzed with multivariable linear regression, adjusting for demographic, comorbidity, and voice use variables. Results: Of the 101 patients enrolled, 75 completed the study. The mean (SD) age of the 75 completing participants was 55.7 (11.8) years and 53 (71%) were women. The participants who completed the study had mean (SD) voice-related work productivity impairment of 43% (27%) at baseline and 22% (23%) at 1 month after BoNT injection (difference, 20% [27%] improvement; 95% CI, 14%-27%; effect size, 0.74). Conclusions and Relevance: This case series study found that employed patients with spasmodic dysphonia reported voice-related work productivity impairment, which improved significantly 1 month after treatment with BoNT injection. The association of spasmodic dysphonia with voice-related work productivity appeared greater in women than men with comparable outcomes with BoNT treatment, but this exploratory sex-associated difference requires independent validation.

The impact of cow size on cow-calf and postweaning progeny performance in the Nebraska Sandhills.

Optimizing beef production system efficiency requires an understanding of genetic potential suitable for a given production environment. Therefore, the objective of this retrospective analysis was to determine the influence of cow body weight (BW) adjusted to a common body condition score (BCS) of 5 at weaning-influenced cow-calf performance and postweaning steer and heifer progeny performance. Data were collected at the Gudmundsen Sandhills Laboratory, Whitman, NE, on crossbred, mature cows (n = 1,607) from 2005 to 2017. Cow BCS at calving, prebreeding, and weaning were positively associated (P < 0.01) with greater cow BW. Increasing cow BW was positively associated (P < 0.01) with the percentage of cows that conceived during a 45-d breeding season. For every additional 100-kg increase in cow BW, calf BW increased (P < 0.01) at birth by 2.70 kg and adjusted 205-d weaning BW by 14.76 kg. Calf preweaning average daily gain (ADG) increased (P < 0.01) 0.06 kg/d for every additional 100-kg increase in cow BW. Heifer progeny BW increased (P < 0.01) postweaning with every additional 100-kg increase in dam BW. Dam BW did not influence (P ≥ 0.11) heifer puberty status prior to breeding, overall pregnancy rates, or the percentage of heifers calving in the first 21 d of the calving season. Steer initial feedlot BW increased by 7.20 kg, reimplant BW increased by 10.47 kg, and final BW increased by 10.29 kg (P ≤ 0.01) for every additional 100-kg increase in dam BW. However, steer feedlot ADG was not influenced (P > 0.67) by dam BW. Hot carcass weights of steers were increased (P = 0.01) by 6.48 kg with every additional 100-kg increase in cow BW. In a hypothetical model using the regression coefficients from this study, regardless of pricing method, cow-calf producers maximize the highest amount of profit by selecting smaller cows. Overall, larger-sized cows within this herd and production system of the current study had increased reproductive performance and offspring BW; however, total production output and economic returns would be potentially greater when utilizing smaller-sized cows.

Swallowing Patterns in the HNC Population: Timing of Penetration-Aspiration Events and Residue.

OBJECTIVE: This study described swallowing patterns in a large head/neck cancer (HNC) cohort. STUDY DESIGN: In a retrospective review of data from a randomized controlled trial, we studied timing of penetration events as they related to aspiration and oral/pharyngeal residue. SETTING: Retrospective review of a multicenter randomized controlled trial. SUBJECTS AND METHODS: In total, 168 patients who were >3 months postradiation received baseline modified barium swallow evaluations. Retrospective analyses of data from these exams were studied, including Penetration-Aspiration Scale (PAS) scores and timing of these events (before, during, or after the swallow), as well as percentage of oral and pharyngeal residue. RESULTS: Aspiration occurred more frequently after than before or during the swallow (P < .05). There were significantly more events of penetration that led to aspiration after the swallow (n = 260) when compared to events before (n = 6) or after (n = 81) the swallow. There was more pharyngeal (16%-25%) than oral residue (5%-20%). Weak correlations were found between thin liquid, nectar-thick liquid, pudding residue, and PAS scores, with varying significance (pharyngeal residue/PAS rs: .26*, .35*, .07*; oral residue/PAS rs: .21*, .16, .3; *P < .05). CONCLUSION: The predominant pattern for this sample of postradiation patients with HNC with dysphagia was aspiration that occurred after the swallow, rather than before or during the swallow. The aspiration was directly caused by penetration events that occurred during the swallow, resulting in aspiration as the airway reopened. Patients demonstrated more pharyngeal residue than oral residue, but a weak relationship was found between residue and penetration/aspiration events. These results guide clinicians in targeting appropriate swallowing interventions.

The minimal clinically important difference of the dyspnea index in laryngotracheal stenosis.

OBJECTIVE: The Dyspnea Index (DI) is a validated patient-reported outcome (PRO) instrument that has been used in the management of laryngotracheal stenosis (LTS). The minimal clinically important difference (MCID) is an established concept to help determine the change in a PRO instrument that reflects meaningful change for the patient. It is not known what change in the DI is of clinical significance in airway surgery. This study aims to determine the MCID for the DI in patients undergoing surgical treatment for LTS. METHODS: This is a prospective cohort study in which 26 patients with LTS completed the DI (score range 0 to 40) before and 6 to 8 weeks postoperatively, in addition to a Global Ratings Change Questionnaire (GRCQ), scored from -7 to +7, at the postoperative interval. A hypothesis test was carried out to test the association between GRCQ and change in DI. The MCID for change in DI was determined using anchor-based analysis. RESULTS: Overall mean change in DI was -11, and mean change in GRCQ was +5. Change in DI scores were significantly different among the improvement and no improvement groups (P value <0.002). Area under the receiver operating curve was 0.92, demonstrating high discriminatory ability of the change in DI score. A change of -4 was determined to be the threshold that discriminated between significant improvement and no improvement. CONCLUSION: A decrease of 4 in the DI can be considered as the MCID for patients with LTS after surgical treatment. LEVEL OF EVIDENCE: 2b Laryngoscope, 130:1775-1779, 2020.

Current Opioid Prescribing Patterns after Microdirect Laryngoscopy.

BACKGROUND: The prevalence of opioid abuse has become epidemic in the United States. Microdirect laryngoscopy (MDL) is a common otolaryngological procedure, yet prescribing practices for opioids following this operation are not well characterized. OBJECTIVE: To characterize current opioid-prescribing patterns among otolaryngologists performing MDL. METHODS: A cross-sectional survey of otolaryngologists at a national laryngology meeting. RESULTS: Fifty-eight of 205 physician registrants (response rate 28%) completed the survey. Fifty-nine percent of respondents were fellowship-trained in laryngology. Respondents performed an average of 13.3 MDLs per month. Thirty-four percent of surgeons prescribe opioids for over two-thirds of their MDLs, while only 7% of surgeons never prescribe opioids. Eighty-eight percent of surgeons prescribed a combination opioid and acetaminophen compound, hydrocodone being the most common opioid component. Many surgeons prescribe non-opioid analgesics as well, with 70% and 84% of surgeons recommending acetaminophen and ibuprofen after MDL respectively. When opioids were prescribed, patient preference, difficult exposure and history of opioid use were the most influential patient factors. Concerns of opioid abuse, the physician role in the opioid crisis, and literature about postoperative non-opioid analgesia were also underlying themes in influencing opioid prescription patterns after MDL. CONCLUSIONS: In this study, over 90% of practicing physicians surveyed are prescribing opioids after MDL, though many are also prescribing non-opioid analgesia as well. Further studies should be completed to investigate the needs of patients following MDL in order to allow physicians to selectively and appropriately prescribe opioid analgesia postoperatively.
